Spira® is an advanced footwear brand premised upon a patented and patent pending footwear technology called WaveSpring® Technology.
The WaveSpring® is a stable and lightweight spring that is placed in the heel and forefoot of our shoes. Each spring is calibrated based upon the size of the shoe and helps protect against fatigue, stress, shock and impact forces.
“I can run in any brand of shoe. I chose to run Spira® because the shoes work for me better than any other brand. The WaveSpring® is a significant advancement in shoe technology. It reduces stress and fatigue and helps me to stay injury free.”

“Having worn Spira running shoes from their inception, it has always been at the top of the list and rotation; whether it be the training shoe or the racing flat. When I go to a race, the Stingers or the XLT’s carry me to PR’s. When I’m training in my Spira® they are there to protect my back, knees, and feet.”
